We're going to replace the entire system, so you'll need to back up any files you've modified. Most likely, this is just
the database.php file, which is stored in system/cms/config/database.php and contains your database connection details.

If you are using a GUI, take care you don't miss any "hidden" files like .htaccess when copying.

Additionally, you'll want to back up any addons that you've added to the addons directory. We'll be replacing this entire
folder, so back those up.

These folders need to be writable (chmod 777) or "Writable by Everyone", and may have had their permissions reset when
you uploaded them to your server. Make sure they are still writable, along with all of their contents.

The comment_helper.php has been removed, meaning display_comments() is gone. Normally we try to deprecate things nicely,
but this just had to go. Instead of calling just that function now you have more control over whether or not to show the
existing comments and the form itself separately. Here is an example of the blog module:

This entry_title, singular and plural logic matches the Keywords structure, where you pass a language key
or just an arbitrary string like "Chicken" to help identify multiple types of data within the same module.
